74ACTQ16543SSCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACTQ16543SSCX is a 16-bit registered transceiver featuring 3-STATE outputs. It utilizes FACT Quiet Series technology for improved dynamic threshold performance and guaranteed simultaneous switching noise levels. The device contains two sets of D-type registers for temporary data storage, allowing independent control of each byte or full 16-bit operation via shorted controls. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Utilizes FACT Quiet Series technology with GTO output control and undershoot correction for superior noise performance.
• Features independent A and B bus registers with separate latch enable and output enable inputs for flexible data flow control.
• Provides back-to-back register architecture supporting multiplexed real-time and stored data transfers.
• Guarantees pin-to-pin output skew and specific dynamic threshold performance limits.

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data bus interfacing requiring registered buffering.
• Systems needing independent byte-level control over bidirectional data flow.
• Applications demanding low simultaneous switching noise in dense logic environments.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant required, as the datasheet lists both MS56A (SSOP) and MTD56 (TSSOP) options. Confirm that the 'X' suffix corresponds to the Tape and Reel packaging format if applicable. Ensure compatibility with the 4.5V to 5.5V supply voltage range and check for any RoHS compliance documentation relevant to the manufacturing date.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when 16-bit width and registered output capability are necessary for signal integrity. The ACTQ series offers enhanced noise immunity compared to standard AC logic. Consider the 56-lead package constraints and ensure the design accommodates the separate control pins for OE, CE, and LE functions for each byte direction.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Fairchild/ON Semiconductor ACTQ family, which integrates Advanced CMOS Technology with Quiet Series features. It serves as a 16-bit version of the ACTQ543, providing registered transceiver functionality. The product line emphasizes reduced electromagnetic interference through controlled output slew rates and noise suppression techniques.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct equivalents such as the 74ACT543 or other 16-bit registered transceivers from compatible manufacturers. Verify pinout compatibility and electrical specifications, particularly propagation delays and output drive currents, before substitution.
